[0002] In the field of industrial automation, oil valves are core components of fluid control systems, and their assembly accuracy directly affects sealing performance and service life. Traditional oil valve assembly relies on manual operation, requiring the valve seat, spring, and valve cover to be manually loaded step by step, resulting in low work efficiency. Due to the small size of the spring, it is easily deformed, and manual placement can easily lead to tilting or misalignment, affecting the verticality of the valve cover pressing. The valve cover needs to be precisely aligned and fastened with the valve seat, and manual operation makes it difficult to ensure consistent angles, resulting in a low yield rate of assembled oil valves.

[0030] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this application proposes an automated oil valve assembly device, which includes a workbench 1 and a conveyor line 2 mounted on the workbench 1. A fixture 21 is mounted on the conveyor line 2. Along the output direction of the output line 2, a valve seat loading station 101, a spring loading station 102, a valve cover loading station 103, and a unloading station 104 are sequentially arranged. A spring loading mechanism 3 and a valve cover loading mechanism 4 are respectively mounted on the workbench 1 at the spring loading station 102 and the valve cover loading station 103. By sequentially loading the valve seat, spring, and valve cover into the fixture, the automated assembly of the oil valve is completed, effectively improving assembly efficiency and the accuracy of the assembled product.

[0032] In this embodiment, an external loading robot (not shown) is provided at the valve seat loading station to connect to the upstream valve seat production equipment. It grabs the valve seat from the valve seat production equipment and transfers it to the fixture at the valve seat loading station. The fixture is adapted to the valve seat to ensure that the valve seat placed in the fixture is at the same angle. Then, the conveyor line carries the fixture containing the valve seat to other subsequent stations.

[0033] like Figure 1-2 As shown, the spring feeding mechanism 3 includes a tray 31 for loading springs, a tray palletizer 32 for feeding the tray 31, a transfer assembly 33 for transferring springs, and a spring feeding assembly 34 for feeding springs. The transfer assembly 33 is used to remove the springs one by one from the tray and transfer them to the spring feeding assembly 34, which then assembles the springs into the valve seats in the fixture 21. The tray palletizer is a conventional device in the art, used for loading full trays and recycling empty trays; its specific structure will not be described in detail here.

[0034] like Figure 1-2 As shown, the transfer assembly 33 includes a transfer robot 331 mounted on the worktable 1. The movable end of the transfer robot 331 is connected to a first rotary drive 332, and the output end of the first rotary drive 332 is connected to a first electromagnetic adsorption component 334 via a connecting support plate 333. Preferably, the adsorption end of the first electromagnetic adsorption component 334 is configured as an arc-shaped structure, the curvature of which matches the circumferential curvature of the spring. When the connecting support plate 333 is in a vertical state, the adsorption end of the first electromagnetic adsorption component 334 is horizontal, and it can adsorb the springs horizontally placed on the tray from the axial direction. After the first rotary drive 332 drives the connecting support plate 333 to rotate 90°, the connecting support plate 333 is in a horizontal state, turning the springs adsorbed by the first electromagnetic adsorption component 334 to a vertical state.

[0035] like Figure 1-2 As shown, the spring feeding assembly 34 includes a spring feeding actuator, a first lifting drive 344 that drives the spring feeding actuator to rise and fall vertically, and a first lateral movement module 345 that drives the first lifting drive 344 to move horizontally. The first lateral movement module 345 is mounted above the spring feeding station of the conveyor line 2 via a first support frame 346.

[0036] like Figure 1-2 As shown, the spring feeding actuator includes a mounting plate 341 connected to the lifting end of the first lifting drive 344. A second electromagnetic adsorption component 342 is disposed on the lower end face of the mounting plate 341. A vertically extending guide pin 343 is disposed at the center of the lower end face of the second electromagnetic adsorption component 342. The diameter of the guide pin 343 is smaller than the inner diameter of the spring to ensure that the spring can be sleeved on the circumference of the guide pin 343.

[0037] like Figure 1-2As shown, the first electromagnetic adsorption component 334 of the transfer component 33 drives the spring to move, so that it is sleeved around the guide pin 343. The second electromagnetic adsorption component 342 is energized and adsorbs the spring shaft end. After the first electromagnetic adsorption component 334 is de-energized, it separates from the spring. The second electromagnetic adsorption component 342 continues to hold the spring. The first transverse module 345 drives the first lifting drive component 344 to move above the fixture. The first lifting drive component 344 drives the spring feeding actuator to descend until the lower end of the guide pin 343 reaches the center of the valve seat in the fixture. The second electromagnetic adsorption component 342 is de-energized, the spring falls into the valve seat, and the guide pin 343 is disengaged from the spring under the action of the first lifting drive component 344, thus completing the spring feeding.

[0038] like Figure 1 and 3 As shown, the valve cover feeding mechanism 4 includes a vibratory feeder 41 for feeding material, a first straight material channel 42 connected to the vibratory feeder 41, a material distribution assembly 43 located at the end of the first straight material channel 42 away from the vibratory feeder, and a valve cover feeding assembly 44 located above the material distribution assembly 43 for transferring and feeding the valve covers separated by the material distribution assembly 43. A matching straight vibrator is provided below the first straight material channel 42 to achieve continuous vibration and material discharge from the first straight material channel 42.

[0039] like Figure 1 , 3 As shown in Figure 4, the material distribution assembly 43 includes a material distribution component 431 located at the discharge end of the first straight material channel 42 and a first transverse drive component 433 that drives the material distribution component 431 to move laterally. The transverse movement direction of the material distribution component 431 is orthogonal to the discharge direction of the first straight material channel 42. The material distribution component 431 includes a receiving limiting plate 4311, and a receiving groove is provided on the side of the receiving limiting plate 4311 near the first straight material channel 42. The receiving groove is used to accommodate a single valve cover, and a receiving fixture 4312 is provided in the receiving groove. Once a single valve cover fed through the first straight material channel 42 is received in the receiving groove, the first transverse drive component 433 drives the material distribution component 431 to move laterally, and the receiving groove is misaligned with the discharge end of the first straight material channel 42 to realize the sequential discharge of valve covers.

[0040] like Figure 1 , 3 As shown in Figure 4, furthermore, the material distribution assembly 43 is equipped with an angle adjustment unit. Since the valve cover is placed at a random angle through the first straight material channel 42, the feeding angle of the valve cover in the material trough needs to be corrected and unified before feeding to ensure that the valve cover can be accurately installed on the valve seat in the fixture.

[0041] like Figure 1 , 3 As shown in Figure 4, specifically, the angle adjustment unit includes a second rotary drive member 4313 that drives the receiving fixture 4312 to rotate horizontally, and a pressing member 432 disposed above the receiving fixture 4312.

[0042] like Figure 1 , 3 As shown in Figure 4, in Embodiment 1, the upper end face of the receiving fixture 4312 has a raised positioning boss 4314. The positioning boss 4314 is configured to conform to the groove at the bottom of the valve seat, and the positioning boss 4314 and the groove of the valve seat are in clearance fit. Correspondingly, the pressing member 432 includes a lifting connecting plate 4322, a second lifting cylinder 4321 that drives the lifting connecting plate 4322 to rise and fall vertically, and a lifting guide rod 4323 that moves through the lifting connecting plate 4322. The upper end of the lifting guide rod 4323 is connected to a limit block 4324, and the lower end is connected to a pressing block 4325. A first elastic member 4326 is circumferentially sleeved on the lifting guide rod 4323, and the two ends of the first elastic member 4326 are restricted between the lifting connecting plate 4322 and the pressing block 4325. A proximity sensor 4327 is provided on the upper surface of the lifting connecting plate 4322 via a vertical support plate to detect the position of the limiting block 4324 in the vertical direction. When the first elastic element 4326 is not compressed, there is a gap between the limiting block 4324 and the proximity sensor 4327.

[0043] Specifically, the valve cover is vibrated and fed onto the receiving fixture 4312 through the first straight material channel 42. Since the valve cover is in a disordered state when it is fed, when the valve cover reaches the receiving fixture 4312, the bottom groove of the valve cover may not be matched with the positioning boss 4314, and the valve cover is mounted on the positioning boss 4314. At this time, the second lifting cylinder 4321 above drives the lifting connecting plate 4322 to move downward, the lowering block 4325 presses on the valve cover, the lifting guide rod 4323 moves upward, the first elastic element 4326 is compressed, and the proximity sensor 4327 detects the limiting block 4324; the second rotating drive 4313 drives the receiving fixture 4312 to rotate until the positioning boss 4314 of the receiving fixture 4312 is locked in the bottom groove of the valve cover. At this time, the valve cover falls, the lifting guide rod 4323 moves downward under the elastic action of the first elastic element 4326, the proximity sensor 4327 detects the descent of the limiting block 4324 and sends a signal that the valve cover has been lowered into place, thereby completing the valve cover angle adjustment.

[0044] like Figure 1 , 3As shown in Figure 5, in Embodiment 2, the receiving limiting plate 4311 has a horizontally extending guide groove that communicates with the receiving groove. A single-acting cylinder 4315 is provided on the receiving limiting plate 4311, with its piston rod positioned within the guide groove and its end connected to a locking block 4316. The end of the locking block 4316 conforms to the locking groove on the side wall of the valve cover. The pressing component 432 includes a lifting connecting plate 4322, a second lifting cylinder 4321 that drives the lifting connecting plate 4322 to move vertically, a rotatable pressing block 4325 mounted on the lifting connecting plate 4322, and a third rotary drive component 4328 that drives the pressing block 4325 to rotate. Preferably, a rubber pad is provided on the lower end face of the pressing block 4325 to increase the friction between the pressing block 4325 and the valve cover.

[0045] Specifically, in the initial state, the piston rod of the single-acting cylinder 4315 is in the extended state, and the locking block 4316 is partially located in the receiving groove; the valve cover is vibrated and fed onto the receiving fixture 4312 through the first straight material channel 42. Since the valve cover is fed in a disordered state, when the valve cover reaches the receiving fixture 4312, the outer wall of the valve cover pushes against the locking block 4316, forcing the piston rod of the single-acting cylinder 4315 to retract; at this time, the second lifting cylinder 4321 above drives the lifting... The connecting plate 4322 moves downward, and the lower pressing block 4325 presses onto the valve cover. The second rotary drive 4313 drives the receiving fixture 4312 to rotate, and the third rotary drive 4328 drives the lower pressing block 4325 to rotate in the same direction, so as to drive the valve cover to rotate synchronously until the locking groove on the side wall of the valve cover corresponds to the guide groove. At this time, the piston rod end of the single-acting cylinder 4315 extends out, and the locking block 4316 is locked in the locking groove of the valve cover, thereby completing the valve cover angle adjustment.

[0046] like Figure 1 , 3 As shown in Figure 6, the valve cover loading assembly 44 includes a clamping component 441, a first lifting drive module 442 that drives the clamping component 441 to move vertically, and a second lateral movement drive module 443 that drives the first lifting drive module 442 to move laterally. The second lateral movement drive module 443 is mounted above the valve cover loading station of the conveyor line 2 via a second support frame 444, and is used to transfer and load the valve cover and install the valve cover into place.

[0047] like Figure 3 , 6As shown in Figure 7, the clamping component 441 includes a mounting frame 4411. A clamp sleeve 4412, which is shaped to conform to the valve cover, is disposed on the lower end surface of the mounting frame 4411. The center of the clamp sleeve 4412 has a receiving area for accommodating the valve cover. Clamping arms 4413 are disposed on opposite sides of the clamp sleeve 4412. A conforming clamping buckle 4414 is connected to the inner side of the clamping arm 4413 near the receiving area through a second elastic member 4415. Under normal conditions (without external force), the conforming clamping buckle 4414 protrudes into the receiving area. Since the valve cover has a thin wall and is lightweight, in a specific embodiment, the conforming clamping buckle 4414 clamps the valve cover by pressing against the side wall of the valve cover through the elastic restoring force of the second elastic member 4415.

[0048] The clamping process is as follows: the clamping component 441 moves above the separated valve cover, and the first lifting drive module 442 drives the clamping component 441 to move downwards. The chuck sleeve 4412 is fitted onto the valve cover and moves downwards. During the downward movement, the contoured clamping buckles 4414 on both sides of the chuck sleeve 4412 are pushed outwards by the pressure of the valve cover, and the second elastic element 4415 is compressed. When the chuck sleeve 4412 is in place, the contoured clamping buckles 4414 are pressed inwards against the side wall of the valve cover under the action of the second elastic element 4415. The resulting clamping force is sufficient to prevent the relatively light valve cover from falling out of the clamping component 441.

[0049] Preferably, the lower end of the contour clamping buckle 4414 is designed with an arc-shaped chamfer structure to improve its smoothness during the initial contact and compression process with the valve cover.

[0050] like Figure 3 , 6 As shown in Figure 7, preferably, the lower end of the chuck sleeve 4412 is provided with a positioning block 4416 that conforms to the valve cover locking groove. The lower edge of the positioning block 4416 is set as a pointed tip, and the radial thickness of the positioning block 4416 is greater than the radial depth of the locking groove. During the descent of the chuck sleeve, the positioning block moves downward, and its pointed tip radially presses outward against the locking block 4316.

[0051] like Figure 3 , 6 As shown in Figure 7, the mounting frame 4411 is equipped with a pusher 445 for pushing the valve cover in the receiving area downwards. The pusher 445 includes a second lifting cylinder 4451, the output end of which points downwards and is connected to a pusher rod 4452. The pusher rod 4452 can move downwards into the receiving area and push the valve cover out of the receiving area. When the mounting frame 4411 moves above the fixture of the conveyor line, the second lifting cylinder 4451 drives the pusher rod 4452 to move downwards. The pusher rod 4452 pushes the valve cover away from the receiving area and continues to move downwards, completing the engagement of the valve cover and the valve seat.

[0052] like Figure 3 , 6As shown in Figure 7, preferably, the lower end face of the push rod 4452 is provided with a magnetic element 4453 for attracting the top of the spring. During the process of the valve cover being pushed downwards and about to engage with the valve seat, attracting the top of the spring helps guide the spring to remain upright and prevents it from tipping over. Preferably, the lower end of the magnetic element 4453 has an arc-shaped structure to ensure that the attractive force on the spring is concentrated at the spring axis. Preferably, the magnetic element 4453 is threadedly connected to the push rod via a screw, and its distance from the top of the spring can be changed by adjusting the installation height of the magnetic element 4453.

[0053] A corresponding unloading robot (not shown) is installed at the unloading station to grab and unload the assembled oil valves from the fixture.

[0054] In specific embodiments, the first rotary drive, the second rotary drive, and the third rotary drive can be rotary cylinders, etc., and the first transverse drive can be transverse cylinders, transverse slides, etc., without specific limitations or descriptions.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
